Dessert Bars That Satisfy

You know how there are times when you want something to eat, but you’re not sure what it is? Make these, and your craving will probably be satisfied.

My friend Julie from Back to My Southern Roots is the champion of making dessert bars. And every time we chat, she makes me want one, with her latest being these snickerdoodle bars.

That’s what got me started thinking about these oatmeal peanut butter bars. I’d had them before at a lot of different potlucks, so I knew they were “a thing.”

As I did a search for this bar, I discovered dozens of recipes—most of them with the same basic ingredients.

However, some of them had extras, such as salt, baking soda, vanilla extract, and add-ons for flavor. I decided to keep it simple with a basic recipe that you can add to if you want.


I kept the ingredients list short and simple. In fact, this recipe only has 3 items in it.

For exact measurements of each ingredient and full directions, go to the recipe card at the bottom of the page. You can even print out the card by using the “print” button.

Here’s what you’ll need:

  • Peanut butter
  • Honey
  • Oatmeal

Yes, that’s it.

However, you can add anything that you think sounds good. Some delicious add-ons are chocolate chips, peanuts, sprinkles, and small chewy candies. Make it however you want.

You can either add extras to the mixture before it sets or press them into the top. If I have mini chocolate chips, I like to press those into the top.


People who know me well know that I do everything the easy way. I always start out with the original recipe and then find shortcuts.

The beauty of this recipe is that I didn’t have to figure out any shortcuts because it’s so simple to begin with. I just made these bars, let them set, and … ate them. Can’t get any easier than that. And they are so delicious!

To make these bars, you’ll need a pan, of course. I used a 7” by 11” pan and covered it in foil.

Since I hate extensive cleanups, I coated the foil in nonstick cooking spray. I love that stuff because it makes life so much easier.

Set the pan aside and start working on the recipe. This is the fun part.

First, put the peanut butter in a medium-size saucepan. Turn the burner on medium heat so the contents of the pot can melt.

Secondly, add the honey to the peanut butter and start stirring. It’s so pretty with different shades of golden swirls.

You’ll need to continue stirring until both ingredients are well mixed. As the mixture heats up, it becomes super easy to do.

Next, pour the uncooked oatmeal into the mixture. Stir until all of the oatmeal is well mixed.

Pour the mixture into the greased pan. Press it down so it’s at an even level all over. If you want to add something to the top, do it now.

Then, place the pan in the refrigerator and let the mixture set for at least an hour. This gives the oatmeal time to absorb the moisture from the peanut butter and honey.

Final Step

Finally, pull the pan out of the fridge and cut your masterpiece into bars.

Foil lifted from the pan

It’s easier to cut if you have it on foil. Just lift the foil from the pan, and you have better access to the edges.

If the bars start to crumble where you’re cutting, heat your knife by running it under hot water.

    3. After they’ve melted together, remove the mixture from the heat.
